The Ipix patent was upheld in the case of INTERACTIVE PICTURES v INFINITE PICTURES but has also been challenged by Ford Oxaal of Pictosphere, aka Mind's-Eye View, who also holds patents related to panorama photography. Oxaal and Ipix settled a lawsuit in 2002 or 2003 (date, please?). In 2003, Ipix initiated another lawsuit against Oxaal. In response to this new suit, Oxaal's lawyers filed this brief which contains several challenges to the validity of Ipix's patent. Apparently the case has not been heard in court yet (as of December 9, 2004).
